----------------------------------
Summary: TSHttpTxnClientAddrGet and TSHttpTxnIncomingAddrGet may
return NULL
Key: TS-4896
URL: https://issues.apache.org/jira/browse/TS-4896
Project: Traffic Server
Issue Type: Bug
Components: Core
Reporter: Susan Hinrichs
With the clean up rearranging to ensure SSN close occurs after TXN close
(TS-4507), the API calls TSHttpTxnClientAddrGet and TSHttpTxnIncomingAddrGet
may return NULL. This can occur in the case where the client connection has
terminated, but the HttpSM has not yet shutdown. We now null out the reference
in HttpSM to the client_vc. These calls fetch the addresses from the
client_vc, so it HttpSM reference to it has been removed, these API's will
return NULL.
Locally, we copy these addresses into the ProxyClientSession before the
client_vc is disconnected. We had push back from deployed plugins for a short
term fix.
Not clear what if anything we want to do in open source. But wanted people to
be aware that this is an issue.
